For starters, I don't know RM's topology or the operting points he used. However, if his designs allowed many different tubes to be used, it suggests that he didn't go for extremes of either voltage or current - commendable 'middle of the road' stuff.Not wishing to offend, I must say that I don't think the Leak Stereo 20 would be a good starting point for experimenting, unless you are prepared to do a lot of redesign, rebuilding and parts replacement. Even getting it to perform well at its rated power requires that.
The St. 20 has a power transformer that tends to run hot, poor PS smoothing with no choke, and rather 'ordinary' OP transformers. I don't think the rather cost-conscious Harold put any more into it than he had to, to get 10W per channel out. (As you probably gather, I'm not much of a Leak fan).
